Yii Application Requirement Checker


Description

This script checks if your server configuration meets the requirements for running Yii application. It checks if the server is running the right version of PHP, if appropriate PHP extensions have been loaded, and if php.ini file settings are correct.

There are two kinds of requirements being checked. Mandatory requirements are those that have to be met to allow Yii to work as expected. There are also some optional requirements being checked which will show you a warning when they do not meet. You can use Yii framework without them but some specific functionality may be not available in this case.

Conclusion

Your server configuration satisfies the minimum requirements by this application.
Please pay attention to the warnings listed below and check if your application will use the corresponding features.
